What's in Bloom

July Blooms

A visit to Mainau Island is an unforgettable experience at any time of year. Here you will find a selection of flowers, trees and shrubs that you can discover during a walk in July:

The gooseneck loosestrife and the montbretia (Crocosmia masoniorum) 'Lucifer' make a devilishly handsome couple in the Shrub Garden [44].

The tousled flowers of the crimson beebalm or scarlet beebalm enrich the prairie-like and natural planting in the Shrub Garden [44].

The bears’s breeches (Acanthus) with their showy blossoms grow on the Roof Garden [48] and in the flowerbeds on the shore of Lake Constance near the Italian Style Flower and Water Cascade [37].

The southern magnolia or bull bay (Magnolia grandiflora) is an impressive tropical shrub with large, white blossoms. It can be seen, amongst others, in the Shrub Garden [44] and in the Italian Rose Garden [33].

Often a single flower of the daylily (Hemerocallis) only lasts one day. You are welcome to admire their beauty in the Shrub Garden [44].

July is the month of hydrangeas on Mainau Island: The Hydrangea Walk [51] and the Roof Garden [48] present varieties of the popular plant with its colorful flower heads.

In the Arboretum (Tree Collection) [25], the Japanese hornbeam (Carpinus japonica) shows its fruits, which resemble hops.

Globe thistles (Echinops) and their spherical flower heads set optical accents among the plants in the Shrub Garden [44].

Tight clusters of rose-purple flowers are characteristic for purpletop vervain, clustertop vervain or Argentinian vervain (Verbena bonariensis). It almost seems to float among the summer blossoms in the flowerbeds and in the Shrub Garden [44].

Purple coneflowers (Echinacea) are popular summer-blooming shrubs. They can be seen among the summer blossoms in the flowerbeds and in the Shrub Garden [44].

Pure elegance: Black hollyhocks (Alcea rosea ‚Nigra') present their black and dark red flowers in the Shrub Garden [44].

In the Herb Garden [11], you will find medicinal herbs which are still in use, for example milk thistle, lavender, arnica and gingko.

In the Dahlia Garden [38] and the Beer Garden at the harbor [49], the Persian silk tree (Albizia julibrissin) carries its pink flowers, looking like silky threads.

The southern catalpa (Catalpa bignonioides) with its trumpet shaped flowers is located next to the Comturey at the harbor [47] and invites you to linger for a while.

Globe artichokes (Cynara scolymus) can not only look good on a pizza, but also in the garden. This beautifully flowering medicinal plant grows in the Kitchen Garden [21].
