Photos do not do justice to this little beauty. Grew it for the first time this year and it will definitely be a permanent fixture in my garden. The seed packet said it doesn't transplant well so I started them in peat pots which worked nicely. They are blooming profusely in containers in my garden.

Gorgeous blooms until frost and so easy to grow from seed sown directly outdoors.

My 'Silver Cup' Lavatera easily outgrew the usual listed height of 24". To be sure I wasn't exaggerating, I ran out there with a tape measure a few minutes ago. A majority of the plants reached 3' with no special care and the tallest of them reached 68"!

Lavatera 'Siver Cup' is a wonderful plant that flourishes with very little care. It grows easily from seed and just flowers its little heart out until frost in my zone 5b garden. Flowers are abundant and seed is both easy to collect and easy to identify. I love this plant and wouldn't be without it!
