We would like to know how tall this plant gets & the size of the blooms.

Hi Kathy -

The four Crescendos we offer have a little different habit and bloom size between the four.

Crescendo Orange - height 8-10" with a spreading or sprawling habit. Bloom size is 1-2" across.

Crescendo Primrose - height 12-18" with an upright mounding habit. Bloom size is 2" across.

Crescendo Ivory - height is 12-18" with an upright mounding habit. Bloom size is 2" across.

Crescendo Compact Purple - height is 8-10" with a compact mounded habit. Bloom size is 1" across.

Hope this helps. Please let us know if you have further questions.

Thanks!
