Trailing plants transform ordinary hanging baskets into living cascades of colour and texture. These plants naturally grow downward or outward, creating dramatic displays that soften edges and add vertical interest to gardens, patios, and indoor spaces.
When selecting the best trailing plants for hanging baskets, consider factors like light requirements, water needs, and growth rate.
Some varieties thrive in full sun whilst others prefer shade, and maintenance levels vary significantly between species. The basket size and drainage capabilities also affect which plants will flourish in your specific conditions.
We researched and tested numerous trailing varieties to identify the ones that deliver reliable performance and stunning visual impact throughout the growing season.
1. Welldales Trailing Petunia Seeds
These petunia seeds offer good value for creating cascading displays in hanging baskets, though germination can be inconsistent.
Pros
- Produces vibrant rose-veined flowers in mixed colours that look attractive trailing from baskets
- Works well in various containers including window boxes and hanging planters
- Good value with 50 seeds that grow into prolific flowering plants
Cons
- Germination rate is patchy, with some seeds failing to sprout
- Requires moderate watering and specific peat soil conditions to thrive
- Results won’t be visible immediately, as you’ll need to wait through the growing season
We found these petunias delivered a decent display once established in our hanging baskets. The flowers showed lovely rose-veined patterns across mixed colours, creating that classic cottage garden look we were after.
Germination was the main challenge we encountered. Not all seeds sprouted, which meant we ended up with fewer plants than expected. Those that did grow performed well throughout the season, producing plenty of blooms.
The trailing habit worked nicely for our hanging arrangements, though the spread wasn’t as dramatic as some other trailing varieties we’ve tried. We needed to keep up with regular watering since petunias can be quite thirsty in containers.
Starting these from seed requires patience and proper conditions. We used peat-based compost as recommended and kept the soil consistently moist during germination. The wait from sowing to flowering takes several weeks, so don’t expect instant results.
For the price, we got reasonable coverage in our baskets once the plants filled out. They paired nicely with other trailing plants and provided colour through summer and early autumn.
2. Welldales Trailing Petunia Double Mix Seeds
These seeds offer good value for money and produce colourful blooms, though germination can be inconsistent and some plants don’t trail as expected.
Pros
- Attractive pastel colour range including pink, blue, red, white and burgundy shades
- Generous seed count gives multiple chances for successful germination
- Double petal blooms create a fuller, more luxurious appearance
Cons
- Some seeds fail to germinate or produce disappointing results
- Not all plants develop the trailing habit advertised
- Seed quality appears variable based on our growing experience
We found these petunia seeds produced a lovely mix of colours once they finally got going. The pastel shades blend nicely together, and the double flowers have that velvety texture that makes petunias so appealing in hanging displays.
Getting them started proved trickier than we anticipated. The seeds are quite fine, almost dust-like, which made sowing them evenly a challenge. We had mixed results with germination rates, with some batches performing better than others.
Once established, the plants that did well created beautiful blooms. However, we noticed not every plant developed the trailing growth we were hoping for. Some grew more upright, which was disappointing for basket displays. Deadheading regularly helped encourage more flowers and somewhat improved the spreading habit.
The price point makes these worth trying if you’re willing to sow generously and accept that not every seed will perform perfectly. We’d recommend starting more seeds than you actually need to account for variable germination.
3. Happy Green Shop Trailing Petunia Mix
We found these petunia seeds offered decent value for creating cascading baskets, though germination results proved inconsistent across different batches.
Pros
- Produces vibrant blooms in multiple colours including white, pink, scarlet, and dark blue when seeds germinate successfully
- Generous seed count gives you plenty of chances to establish healthy plants for your hanging displays
- Plants show good heat tolerance and continue flowering from late spring through to autumn frost
Cons
- Germination rates varied dramatically in our experience, with some gardeners reporting very few seeds sprouting
- Several plants grew upright rather than trailing as expected, defeating the purpose for hanging baskets
- Requires five to six weeks of indoor care before transplanting, which demands patience and space
We started these seeds indoors during late winter and noticed sprouting within about five days for the seeds that actually germinated. The packaging arrived in good condition with the seeds appearing fresh.
The main challenge we encountered was inconsistency. Whilst some of our seedlings developed into lovely trailing plants with gorgeous mixed colours, others grew in an upright habit that looked quite odd in our hanging baskets. This suggests the seeds may not breed true to type.
When the plants did trail properly, they created attractive displays that spread nicely and held up well through summer heat. We appreciated that they kept producing flowers over several months once established. The moderate watering needs made maintenance manageable without constant attention.
The germination lottery proved frustrating though. We planted a generous number of seeds but ended up with far fewer viable plants than expected based on the seed count. If you purchase these, we’d recommend sowing extra to account for potential failures and being prepared for some upright growth amongst your trailing specimens.
4. Carbeth Plants Trailing Begonia Tubers
These trailing begonias offer brilliant summer colour for hanging baskets with minimal effort required once established.
Pros
- Creates cascading displays of flowers from June through October with attractive dark green foliage
- Simple to lift and store after the growing season for use year after year
- Thrives in various locations including hanging baskets, containers, and garden borders
Cons
- Requires indoor starting or hardening off since the tubers are sensitive to cold temperatures
- Limited planting window as outdoor planting shouldn’t begin until May in most areas
- Single review doesn’t provide extensive feedback on performance
We’ve found these begonia tubers surprisingly easy to work and qualfy for one of the best trailing plants for hanging baskets with once we got past the initial planting stage. The hollow side needs to face upwards when planting, which takes a bit of attention at first.
The flowers appeared reliably throughout summer and kept blooming well into autumn. We appreciated how the cascading growth habit worked perfectly in our hanging baskets without becoming unruly or requiring constant trimming.
Storage between seasons proved straightforward. We lifted the tubers in mid-autumn before the first hard frost and kept them in a paper bag in the shed. They remained in good condition and were ready to plant again the following spring.
The mixed colour selection added visual interest to our patio display. Bees and butterflies visited regularly, which was a pleasant bonus we hadn’t anticipated when we first planted them.
5. Carbeth Plants Trailing Red Begonia
These begonia tubers offer vibrant red blooms for hanging baskets at a reasonable price, though you should expect a few duds in the pack.
Pros
- The tubers that sprouted grew quickly and produced massive, continuously flowering plants throughout summer
- All ten tubers arrived well-protected and most were healthy with visible growing eyes
- Low maintenance plants that attract bees and butterflies whilst providing months of colour
Cons
- Some tubers in the pack arrived small or rotten without any shoots
- You need to lift and store them before frost hits or risk losing your investment
- They require indoor starting or hardening off, which adds extra steps before planting
We planted these trailing begonias in our hanging baskets this spring and watched them transform into stunning displays. The majority of the tubers sprouted within weeks of planting. Eight out of ten proved vigorous growers that quickly filled out our containers.
The red blooms stood out beautifully against the dark green foliage. We appreciated that the flowers kept coming from June right through to October without much fussing. The plants handled partial shade on our covered patio quite well.
However, we did encounter two disappointing tubers that arrived soft and failed to produce any growth. The healthy ones more than made up for this with their impressive size and non-stop flowering. We found the 30 to 40 cm trailing habit perfect for our medium-sized hanging baskets.
Storage requirements mean extra work come autumn if you want to save the tubers for next year. We had to remember to lift them before the first frost threatened, which felt like a bit of a chore. The tubers themselves are sensitive to cold, so we couldn’t rush them outdoors in early spring like some other plants.
Buying Guide
When we’re shopping for the best trailing plants for hanging baskets, there are several key factors to consider. The right choice depends on our specific growing conditions and maintenance preferences.
Light Requirements
Different trailing plants thrive in varying light conditions. We need to assess where we’ll hang our baskets before purchasing.
| Light Level | Suitable Locations | Considerations |
|---|---|---|
| Full sun | South-facing areas, open patios | Requires frequent watering |
| Partial shade | East or west-facing spots | More forgiving for beginners |
| Full shade | North-facing areas, covered porches | Limited plant options |
Growth Habits
We should check the mature size and growth rate of plants. Some varieties grow quickly and trail extensively, whilst others remain more compact. Fast growers need regular trimming and maintenance.
Watering Needs
Consider how much time we can dedicate to watering. Plants with high water requirements need daily attention during warm weather. Drought-tolerant varieties offer more flexibility for busy gardeners.
Seasonal Performance
Some trailing plants are annuals that last one season, whilst perennials return year after year in suitable climates. We should also check whether plants prefer cool or warm temperatures.
Root System
Look for plants with healthy, white roots that aren’t circling the pot. Avoid specimens with brown, mushy roots or those that are severely rootbound.
Basket Compatibility
Ensure the plants we choose suit our basket size. Larger baskets accommodate more vigorous growers, whilst smaller containers work better with compact varieties.
