Veronica

'Ulster Dwarf Blue'

spike speedwell

Featuring a striking display of uniform, straight flower spikes in deep blue, graduating to an almost neon green, you’d be forgiven for thinking that Veronica 'Ulster Dwarf Blue' (or spike speedwell) had been digitally imprinted on your garden! But no, these cyber-coloured flowers are all real, and super tactile too – adults and kids alike won’t be able to resist reaching and stroking the soft and furry spires. Plant the low-height Veronica 'Ulster Dwarf Blue' at the front of borders and in containers, where little (and big) hands can touch away to their hearts content.

The vivid colour combination makes for an electrifying display, but believe or not this trendy variety is a form of that cottage-garden favourite, the speedwell. This means you can expect plentiful deep blue flowers throughout the whole summer season, with regular deadheading – and as a clump-forming perennial it will come back stronger each year, to form an eye-catching mound. Bold blues and greens go with any colour scheme, and Veronica spicata 'Ulster Dwarf Blue' is tough enough to handle a range of growing conditions – so we think there’s a place in every garden for this super-charged specimen.

How to grow perennials

Read the full growing guide
Plant promptly

Unpack bare roots or rhizomes on arrival and plant them within a week. Until then, keep them somewhere cool and ensure the roots remain slightly moist, never wet.

Delivered in a pot?

Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.

Soak the roots

Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.

Pot up or plant out
Pot up or plant out

Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.

Check planting depth
Check planting depth

Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.

Grow them on

Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
