Rudbeckia maxima


Rudbeckia maxima is an overlooked impact plant. This unique giant (the clue is in the name Maxima!)black-eyed Susan has a deciduous basal rosette of waxy blue foliage resembling a cabbage. In late spring through early summer, the flower stalks of Rudbeckia maxima can rise to over 2m tall. At the top of each stalk are large, wide, brown-green centred, yellow daisies. After flowering birds love to eat the seeds. See what I mean!? We should see it more often!

Rudbeckia is a tough summer-flowering perennial that has great presence and grows almost anywhere that isn’t full shade or a pond. It is a tough, low maintenance plant which makes it perfect for wet gardens. Where happy, Rudbeckia spreads into a slowly widening clump that gets more floriferous each year. Rudbeckia flowers attract butterflies and the seed heads are a favourite of goldfinches; and they look great in the autumn when the petals fall off.
