Baptisia australis

One of my favourite perennials for almost any colour border. It flowers all summer and then, with flowers picked or dead-headed, it gives you excellent silvery foliage through the autumn. More

More Details

This is one of the most beautiful early-summer perennials with rich, deep indigo-blue, pea-like flowers. The flower spikes grow to a whopping one metre tall and they keep the drama going through to winter, as their seedpods are equally interesting. A tough plant which will thrive on any free draining soil, and which is especially good for hot, dry areas.

I used 6 seeds (over half the packet I brought) and like all the other purchased seeds I bought at the same time (see other reviews), the Baptisia seeds were sown in individual cells in the same seed tray. I was really disappointed that not one seed germinated. I haven't tried the remaining seeds I have left as I have used up over 50% of the packet without any success to date. Its a shame as all my other seeds purchased from Sarah Raven that were planted at the same time have been successful. Not sure if there are any guarantees with purchases?

You had to send me a replacement plant as the original one was so badly packed thaT the plant was badly damaged.
The replacement one hasn't survived

I have planted these in large pots. They aren’t very tall yet but the flowers are just coming out, so I am expecting a brilliant show soon.

Arrived as a healthy but small plant. Unfortunately it got caught out on a very hot day and burnt and withered. So, I cut it right down, nursed it and it seems to have rallied. It has leaves but I don’t expect it to flower this year.

Tiny plug plants. One has died, the others are still tiny and won’t flower this year. Very poor value for money.

Had a slow start but this was due to slug attack rather than any inherent problem with the plant. Recovering well now but not flowered yet so can’t comment on colour.
