RolesOne spike, one daisy or grassThree thirsty annuals in the same wet clay

Partners have to live the same summer: heat, sun, and a crown that dries. [1] A hosta or iris that wants wet feet will rot the agastache long before the daisy looks unhappy. Keep those in a different bed. Lavender fails in the same wet clay, so it is a fair partner only where both already drain.

What plants go well with agastache?

Echinacea or rudbeckia for daisy color, salvia or lavender for another spike, and a grass that wants drain — not hostas.

Spikes, daisies, and grasses

Give the tall hybrid mid-border room. Compact Kudos can sit closer to the path. Do not jam a wet iris against the agastache crown. Echo one spike color and one daisy, not four competing heights in a three-foot bay. Grasses should stay as a frame, not a wet meadow sedge. Leave a hand of open soil at the agastache crown so winter rain can leave.

Can I plant lavender with agastache?

Yes if both have sun and drain. Lavender fails in the same wet clay that kills agastache.

What to leave out of the bed

  • A shade plant that wants a north wall.
  • Water hyssop or a pond marginal.
  • A rich, wet annual mix that never dries.
  • Garden hyssop as if it were this genus.

Culture stays on How to Grow Agastache.

Share sun and drain. One spike, one daisy or grass. Skip a wet partner at the crown.

FAQ

Do hummingbirds like agastache?

Yes — especially the tubular western types. Pairing still starts with sun and drain, not a bird list.

Can hostas sit with agastache?

No. Hostas want shade and moisture. Agastache wants sun and a dry crown.

Do deer eat the companions too?

Agastache is often left alone. Echinacea and salvia vary. Plan for deer if pressure is high.
