Buckwheat and blue tansy (Phacelia tanacetifolia) have both been found to provide food for predators and parasites of insects.

Suitable plants to attract predators and parasites include blue tansy, coriander, cosmos, lavender, sunflower, and yarrow.

Chemicals recovered from the pottery indicate that in addition to wine there were savory, blue tansy and artemisia — a member of the wormwood family — present.

Phacelia tanacetifolia is a species of phacelia known by the common names lacy phacelia, blue tansy or purple tansy.

Usher in the change of the seasons with the label's latest additions: the Blue Tansy resurfacing mask, Brighten pineapple and gemstone mask and the Pink Clay moisture mask.

For this reason a high thujone oil from Tanacetum vulgare should never be referred to as "Blue Tansy" oil and any such blue oil containing significant thujone is an adulterated product.

Despite claims by some unethical resellers of essential oils who adulterate the very expensive Blue Tansy (Tanacetum annuum) oil with the much cheaper oil from Tanacetum vulgare, it should be noted that the oil from Tanacetum vulgare is never blue in color as it contains no chamazulene.

Tanacetum annuum is often confused with common tansy (Tanacetum vulgare) but the former produces an essential oil that is completely different chemically as it contains no thujone and high amounts of chamazulene making the oil dark blue in color, giving rise to it common name of Blue Tansy Oil.
