Best rudbeckias to grow
Rudbeckias are stars of the late summer garden – we've picked eight of our favourites.
As midsummer flowers start to fade, rudbeckias take over with their cheery yellow blooms.
Flowering from late summer to mid-autumn, rudbeckias are especially suited to prairie-style borders. They combine particularly well with border perennials such as perovskia, eupatorium, echinacea and persicaria.

Rudbeckia 'Aries'
The semi-double blooms of 'Aries' have lovely mahogany-coloured centres that bleed out into the otherwise yellow centres. Like all other rudbeckias with accessible pollen and nectar, it's popular with bees and butterflies.

Frequently Asked Questions
Does rudbeckia come back every year?
Whether your rudbeckia comes back every year depends on which variety of rudbeckia you are growing. Annual varieties will only last for one growing season. Biennial varieties will take two years to complete their life cycle. These usually have orange, dark-red or brown flowers. Perennial varieties, which usually have yellow flowers, will live for more than two years. Check the seed packet or plant label when you buy rudbeckia, to check which variety you are purchasing.
Where is the best place to plant rudbeckia?
Rudbeckias will grow best in full sun. Although they can grow in light shade, they will flower best if grown in a sunny spot.
Does rudbeckia need to be cut back?
More mature plants may require cutting back. Chelsea chop taller varieties in May, reducing their height and removing the need for staking. Perennial varieties will benefit from lifting and dividing every three to five years.
