The trailing stems of Petunia 'Cascadia Rim Magenta' produce a procession of starry-shaped, deep magenta blooms. Each velvety trumpet has a well defined, creamy white margin that makes these flowers really stand out from the foliage. Let this trailing petunia spill from hanging baskets and patio containers for a particularly eye catching display this summer. Height: 30cm (12"). Spread: 40cm (16").

Flowering Months
When all risk of frost has passed, gradually acclimatise petunias to outdoor conditions over a period of 7 to 10 days. Choose a sunny site for their final position. Feed and water plants regularly, particularly during hot, dry periods. Deadhead faded petunia flowers to encourage more blooms to be produced and extend their vibrant display.
Pot up plugs into 9cm pots and grow on for transplanting into final containers or baskets later on. Alternatively, plant plugs directly into flower pouches. Grow petunia plants on in warm frost free conditions. Pinch back the stems while the plants are still young to encourage them to produce bushier growth and more flowers.

What a surprise! 2014-07-27

When I received 6 little 3" plants in an A5 package I was unsure if they would survive but I planted them into a larger pots and waited. When I planted them into their final home along with 3 Dalia plants and 4 left over Lobelia into a 28" dia pot which I had purchased to re plant a bay tree but never got around to it! they all looked a bit lost, but what a surprise within weeks the plants had put on so much growth and filled the pot to overflowing. The best Patunia plants I have ever grown the flowers are stunning and last far longer than the frilly type, best ever, I will get more next year and forget the other types, here's hoping they come in another colour combo soon.

Fabulous display 2014-07-20

These Postiplug plants were very small when I received them, so I was doubtful how they would fare but I needn't have worried. They're in large patio containers along with bi-colour carnations and have developed into strong, compact, bushy plants. One or two turned out to be plain, without the cream margin, but it doesn't matter as they blend well and all are providing a stunning display of blooms that aren't spoiled by rain. An unusual colour too, attracting many compliments. Without doubt, the best petunias I've ever had - will definitely buy more next year!

Stunning plants - very happy customer! 2014-07-16

Stunning display! These are some of the best petunias I have ever had. Compact bushy plants that filled out extremely well and have been a profusion of colour. Unlike other petunias these are not spoiled by rain. They have been beautiful and have received many compliments. Excellent value - would definitely buy again.

Plants arrived! 2014-07-04

My plug plants arrived this morning - this is the first year I've bought plants online - this is the second of my orders to arrive. The first order was for smaller plugs which arrived quickly and looking almost perfect; on this order the roots look healthy and solid, but unfortunately the package was very squashed and the foliage has suffered as a result, many of the little leaves were damaged or broken off, I'm hopeful they will recover but I feel the packaging for this size of plug was inadequate, with only a plastic tray at the base and one soft cardboard fold-over cover to protect the plants, it simply isn't sturdy enough to protect the foliage. I potted the little plants on immediately so am hoping this will help with a speedy recovery. My order was stamped as posted on 03/04 and arrived on 07/04 so 4 days in the postal system probably hasn't helped the plants too much either. They were, however, very good value and I will definitely buy from Thompson and Morgan again.

Excellent plants 2014-01-07

Plug plants arrived in perfect condition, I planted them straight into a flower pouch and now they are blooming wonderfully. So many people are commenting on the flowers and how lovely they look. They brighten up our fence and were so easy to plant up. I really like the colour of this variety of petunia it is not too common hwich emphasises how lovely they are especially with the star shaped flowers. Will definitely be buying these again next year, might just have to buy twice as many.
